POCKET-WINDOW SCREEN.

Specification of Letters Patent.

Patented Mar. 12, 1918.

Application filed June 25, 1917. Serial No. 176,657.

To all whom it may concern Be it known that I, EDMUND H. LUNKEN, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State 01 Ohio, have invented certain new and useful Improvements in Pocket-lVindow Screens, of which the tollowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to screening devices for pocket windows wherein more particularly there are to be two screens,'both of which slide entirely up into the pocket. While some of the features of my invention would be applicable with advantage to single screens, the main object in view is the provision of an arrangement of a plurality of screens capable of complete concealment in an overhead window pocket.

It is the object of the structure herein to simplify to the last degree the structure and operation of pocket window screen installations of the above type, and wherein among other things the screens are of the Lunken interlocking molding type, and have weathering devices for protection of the additional opening on the outside of the window necessary for the accommodation of the screens.

In this device there is provided a spring device which not only serves as a stop for the top screen, due to its special construction, but also .serves as a sutlicient frictional counterbalance for the screens while moving upward into the pocket. Certain improvements are provided in the weathering devices, and the channel members for the screens are designed for easy installation in connection with the other parts of a window of the pocket type.

Also it should be understood that the en tire structure is designed to take up the least possible amount of space. so as to be adapted for installation in houses using standard construction without any essential modification.

The above objects and advantages and other improvements which will be noted I accomplish by that certain construction and of the pocket in arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings,

Fig. 3 is a detail perspective of the corner a window showing the spring stop feature of my invention.

Fig. 4: is a detail perspective showing the means whereby this spring retains the upper screen member in its normal position in the window.

Fig. 5 is another detail perspective showing theintermediatespring stop. I

Fi (3 is a detail perspective view of an alternative form of construction of the outside.

lhe window has side stiles 1, 1, a sill 2 and a wall pocket 3. There are shown two sashes, an upper sash 4: and a lower sash 5, both or" which are adapted to slide up into the pocket. The two sashes are separated by a parting strip 6, and are provided with a special weight pulley device 7. These parts form no part of my present invention, except in so far as the weather joint between the upper rail of the upper sash 4L and the screen device is concerned.

There are two screens shown in the drawings, a lower screen 8 and an upper screen 9. The screens are formed of solid metal frame pieces 10. with wire soldered to them, although this forms no part of the invention. To facilitate the passing of the moldings and the provision of close joints in connection with the weathering they are made of a metal piece which is semioval in cross section. as shown.

The lower screen is provided with an angle plate 11 across the bottom, which rests on the sill and acts as a shoulder for engagement with the outer wall otthe pocketas will be described, and the lower screen is also provided with an extending strip 12which lies bet\veentl1e two moldings of the upper screen when the device is assembled. so as. to form an interlock and permit the lower up in the screen to push up and pull down the upper screen when said former screen is operated.

The wall pocket, which is located overhead, and has an outside wall 13, which is faced with a special shaped molding 14, that confines between it and the wall 13 a piece of weathering material 14* such as felt. This molding has a longitudinal head 15 which may, if desired, be used'as an addi-' tional weather joint, and beneath the bead the molding is cut away to form a shoulder for abutment of the angle plate 11, when the lower screenis pushedup into the pocket.

The guide for the screens is preferably a double width. channel, although it could be a trackway if the screen -ln0ldings were channeled. The double channels are made up of pieces 16 of complete channel form set up intoqthe'pocket and running to the top thereof, and angle pieces 17 having the inner wall only of the channel, and outer trimming strips 18 which are secured to the side of the window frame so as to somewhat overlie the angle pieces 17 and form there with the balance of the channel. The overlap provides an efiective water-seal for'the channel so formed. p The full channel pieces run to a point just slightly below the pocket opening, and form a stop for locating laterally the position of the molding 14.. They are cut away slightly just at the lower end and the stile behind them is cut out at each side to form a pocket for themovable ends of springs 19, which ends are crooked and lie inside said pocket and are held by the said channel pieces against springing out. (F igs.2 and 4.) The springs are secured in the base of the lower channel pieces, e., the angle strips 17, and thus liejust below the opening of the pocket. They act as the stop for preventing the upper screen from falling too low in the window opening, a friction counter-balance for both screens, and a stop for holding-both screens in the pocket. The function as a counter-balance can easily be seen-when it is remembered that the interlocking'molding device causes both screens to pass together upinto the pocket,- and that they will press out against the screens during thismovement and tend to hold them frictionally'. i Asa stop for both screens when they are pocket '(Fig. '3), it can be seen that they will spring out to fill the channel and abut against the angle plate 11 on the lower screen, and with the parts properly setup will preserve the said angle plate inposition against the shoulder beneath the bead on the outside molding l4. For the third function, the upper screen molding is specially shaped by means of cutting it away at 20 (Fig. 4) just beneath th P- stee ere y r ains shoulder below the top frame piece of the upper screen at both upper corners. The springs will move out when this cut-away part is reached and will thus hold the upper screens in place leased'by pressing them inwardly and out of the way.

The upper frame member of the upper screen is provided with a facing piece 21 which makes its molding to fill the channel and slide smoothly. This piece has a like oval shape to the frame proper. T he bead on the top molding 1a is preferably cutaway at 14: behind the pocket channel piece so as to permit the bead to extend flush with the inside of the channel wall, as well as the felt Weatherstrip.

When the upper screen is lowered and held place by the springs at each side, the Weatherstrip will press against its upper frame member, and the window sash isalso drovided with a rounded molding 22 and a Weatherstrip 23 which serve a like function for the inside edges of the upper frame member. When the screens'are in the pocket, this window weathering will abut against the lower screen frame, which also has the rounded feature that gives possibility of closer placing of the parts without chance of the corners catching'so as to prevent easy operation of the parts of the window;

It can be seen that the screen channel in the window opening can easily be made of no greater depth thantheparting strip between the sashes and thus that there will be no unsightly channel pieces which protrude out into the range of vision through the window. The exceedingly simple spring con structionwvith threefold function'gives to this screen arrangement an inexpensiveness of construction and" an ease" of operation which are thought very valuable and useful. By pressing in the springs, the screens can be put at almost any desired position until they are positively reof double width 7 limited only by the interlocking of the "It is not intended that the spirit of this To remove the screens, the outside invention should be construed as applicable only to the exact structure above described, due to my failure to mention-alternative structures during the description. On the contrary, it is my desire that the claims that follow be given in their construction the full advantage of "the doctrine of equivalentsi v o By the term pocket, is meant a space beyond the normal window opening and. the

normal positio of sashes and, screens into which the sashes and screens may slide, whether or not this beentirely inclo'sed between opaque walls or not, i i
